Abstract (en)
The object matter of the invention is an anti-resonant reversible vibrating conveyor, comprising a body in the form of a rigid spatial frame structure, supported symmetrically on resilient supports on the ground and a trough of self-supporting structure, constituting at the same time the mass of the dynamic eliminator, situated inside the body with a clearance enabling its working vibrating motion and connected to it symmetrically by means of resilient elements, as well as two vibrating drive units rigidly connected to the body, in such a way that the direction of action of the forcing resultant force, acts in the longitudinal plane of symmetry of the trough and passes through the centre of mass of the trough and the centre of mass of the conveyor body, which centres of gravity coincide, the vibration drive units being connected to the power source via a control device (2), which is a two-channel tuneable generator with signal amplifier, and the vibration drive (4) are electromagnetic actuators, and furthermore the resilient elements (6) having equal stiffness in the longitudinal directions k<sub>sy</sub> and transverse directions ksx.
